Abstract: A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.

Abstract: A direct carbonaceous material to power generation system integrates one or more solid oxide fuel cells (SOFC) into a fluidized bed gasifier. The fuel cell anode is in direct contact with bed material so that the H2 and CO generated in the bed are oxidized to H2O and CO2 to create a push-pull or source-sink reaction environment. The SOFC is exothermic and supplies heat within a reaction chamber of the gasifier where the fluidized bed conducts an endothermic reaction. The products from the anode are the reactants for the reformer and vice versa. A lower bed in the reaction chamber may comprise engineered multi-function material which may incorporate one or more catalysts and reactant adsorbent sites to facilitate excellent heat and mass transfer and fluidization dynamics in fluidized beds. The catalyst is capable of cracking tars and reforming hydrocarbons.

Abstract: A solids circulation system receives a gas stream containing char or other reacting solids from a first reactor. The solids circulation system includes a cyclone configured to receive the gas stream from the first reactor, a dipleg from the cyclone to a second reactor, and a riser from the second reactor which merges with the gas stream received by the cyclone. The second reactor has a dense fluid bed and converts the received materials to gaseous products. A conveying fluid transports a portion of the bed media from the second reactor through the riser to mix with the gas stream prior to cyclone entry. The bed media helps manipulate the solids that is received by the cyclone to facilitate flow of solids down the dipleg into the second reactor. The second reactor provides additional residence time, mixing and gas-solid contact for efficient conversion of char or reacting solids.

Abstract: A method for calculating the height and the density of a fluidized bed is described. In a first mode of operation, a first differential pressure and a second differential pressure are obtained, a bed density of the fluidized bed is calculated, and a bed height is calculated by dividing the first differential pressure by the calculated bed density. In a second mode of operation the system is purged by using a pressurized gas.

Abstract: A solids discharge system (SDS) is configured to separate solids from product gas. The system includes a solids separation device and at least one solids transfer conduit configured to receive solids from the solids separation device. The solids transfer conduit is selectively partitioned into a plurality of compartments (or “sections”) along its length by isolation valves. A gas supply conduit and a gas discharge conduits are connected to one of the sections to facilitate removal of solids. A filter in fluid communication with that section is configured to prevent solids from passing through the gas discharge conduit so that the solids can be removed from one of the sections of the solids transfer conduit. A product gas generation system incorporates first and second reactors, the latter of which receives products created by the second reactor.

Abstract: A feeder system for advancing a compressible material has a hydraulic circuit associated with a final compression stage. The hydraulic circuit includes a platen attached to a primary ram configured to travel within a primary cylinder. The platen is operatively connected to a main piston cylinder assembly and at least two ancillary piston cylinder assemblies. In a first mode of operation, the hydraulic circuit forces the ancillary piston cylinder assemblies to advance the platen and ram in a forward compression direction until they reach a first predetermined position between travel extremes, while the main piston cylinder assembly passively travels along in the forward compression direction. Once the first predetermined position is reached, in a second mode of operation, the hydraulic circuit additionally forces the main piston cylinder assembly to compress the compressible material. In a third mode of operation, the hydraulic circuit retracts the platen and primary ram.

Abstract: A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.
